3V至5.5V多通道RS - 232线路驱动器/接收器 3-V TO 5.5-V MULTICHANNEL RS-232 LINE DRIVER/RECEIVER
description
The MAX3221 consists of one line driver, one line receiver, and a dual charge-pump circuit with ±15-kV ESD protection pin to pin serial-port connection pins, including GND. The device meets the requirements of A/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. These devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew rate.
